TileServer¶

TileServer-gl is a small node application that can serve vector tiles (mbtiles) for mapbox without the need for an external provider.

The maps Gisaf base layers (the definition file being located in gisaf-app/src/app/map/base_styles.ts) in can be parametered such that a base layer is hosted locally (see the gisaf config file).

Install tileserver-gl-light¶

Unfortunately, it requires a much older version of node (6.x).

yarn global add tileserver-gl-light

Download the mbtiles¶

From: https://openmaptiles.com/downloads/planet/ , and store the relevant one on the server's filesystem (eg. /usr/local/2017-07-03_asia_india.mbtiles)

Service¶

A systemd service configuration file, in /etc/systemd/system/tileserver-gl-light.service:

[Service]
ExecStart=/usr/bin/node /usr/lib/node_modules/tileserver-gl-light/src/main.js --cors true -c /etc/tileserver/conf.json
Restart=always
User=www-data
Group=www-data
Environment=NODE_ENV=production

[Install]
WantedBy=multi-user.target

Configuration¶

Eg, in /etc/tileserver/conf.json:

{
  "options": {
    "paths": {
      "root": "",
      "sprites": "/usr/lib/node_modules/tileserver-gl-light/node_modules/tileserver-gl-styles/styles/osm-bright" 
    },
    "domains": [
      "gis.auroville.org.in" 
    ],
    "styles": {}
  },
  "data": {
    "india-vector": {
      "mbtiles": "/usr/local/2017-07-03_asia_india.mbtiles" 
    }
  }
}

Run the service¶

systemctl enable --now tileserver-gl-light.service

nginx proxy¶

In order the mbtiles to be served by tileserver, add in the nginx conf (adjust eventually):

    location /tiles/ {
        proxy_pass http://127.0.0.1:8080/;
    }
